The Effect of Amazon and Orinoco Rivers on the Sea Surface Temperature and Salinity Cycles off Barbados: A Record from Montastrea sp. and Siderastrea sp. Corals (thesis)
Four Mantastrea sp. coral cores and four Siderastrea sp. coral cores were collected from the west coast of Barbados in June-July 2009. Samples were cut [at] Washington and Lee University in Lexington, Virginia and x-rayed ...
Impacts of Low-Head Dam Construction and Removal with Little Channel Sediment Storage: Case Study from the Maury River, Virginia
Dam removal projects are becoming more frequent as awareness of the negative ecological consequences increases and dams begin to fail. However, due to the potential threats of post-removal channel migration, bank erosion, ...
Can Changes in the Larval Developmental Modes of Olivella in the Caribbean Neogene Be Used as a Reliable Productivity Proxy? (thesis)
The Closure of the Isthmus of Panama functions as an excellent natural experiment because of our knowledge of the geologic record and the changing environment that influence the temperature, salinity, nutrients, and ...
Mangrove Management Strategies for Social and Ecological Integrity
This research seeks to determine if mangrove restoration projects successfully contribute to improved ecological and social well-being in case-studies from three different countries: Colombia, Vietnam, and Kenya. By comparing ...
Geochemical Variability of Obsidian in Western New Mexico with Laboratory- Based pXRF (thesis)
Mule Creek and Mt. Taylor, located in southwestern and western New Mexico respectively, are obsidian source regions for archaeological lithic artifacts. Trace element concentrations can be used to distinguish obsidian from ...
GeoEye-1 Multispectral Satellite Imagery Classification: An Accurate Method for Identifying Populations of Acropora spp. Corals Prior to a Field Study (thesis)
In recent decades Caribbean coral reefs have experienced drastic decline in live coral cover. Some of the main framework-building coral species Acropora cervicornis, Acropora palmata, and the new hybrid species Acropora ...
Hf and Pb Isotope Data for Mafic Lava Flows from the Three Sisters and Newberry Regions of the Central Oregon Cascades (thesis)
The Cascade arc is an end member convergent margin in which the young and slowly subducting slab is hotter than in most subduction zones. Consequently, the timing and location of slab contribution, namely dehydration, is ...
Influence of Late Jurassic Inversion Structures on Sedimentary Basin Uplift, Chukchi Shelf, Offshore Alaska (thesis)
This thesis examines the existence of a reactivated fault interpreted to be an inversion structure associated with a Jurassic tectonic event in the Chukchi Shelf off the NW coast of Alaska. Brookian, Jurassic, Ellesmerian, ...
Tectonic Evolution of the Chugach-Prince William Terrane: U/Pb Detrital Zircon Age and Provenance of Cover Strata to the Paleocene Resurrection Peninsula Ophiolite in Seward, Alaska (thesis)
The southern margin of Alaska is defined by a late Mesozoic to Cenozoic accretionary complex that comprises the Upper Cretaceous to Eocene Chugach-Prince William (CPW) terrane. The Contact Fault serves as the current ...
Late Paleocene-Eocene Syn-Orogenic Fluvial Sedimentation and Detrital Fission Track Thermochronology of Laramide Syn-Orogenic Sediments, Denver Basin, CO (thesis)
This study investigates the Laramide foreland syn-orogenic sediments preserved
in the Denver Basin, CO and interprets the Late Cretaceous-Eocene tectonic and climate
history of Central Colorado. This thesis is divided into ...
